iwlwifi: remove unneeded locks from apm_stop() and stop_master()
Since priv->reg_lock was added to keep multi-access register manipulation
atomic, priv->lock protection is no longer needed. Remove this from
iwl_apm_stop_master() and iwl_apm_stop().
Add warning of timeout when polling for busmaster disablement confirmation,
and some comments.
NOTE: This is needed to enable use of apm_ops.stop() within iwl_eeprom_init();
priv->lock does not get initialized until after this flow. See patch
"remove power-wasting calls to apm_ops.init()"
